My present invention relates to improvements inhand trucks of theone-man type, which, while adapted for handling various loads, isespecially designed for handling barrels, kegs, drums, and other compactand comparativelyheavy loads. Thejtruck of my invention is of that typethat may be trundledor wheeled similar tothe manipulation of awheel,barrow,'but it is supported at three points in order that theentire load maybe carried on three spaced wheels, and the loadedtruck'easily steered.

The primary object of the invention is to I binations and arrangementsof parts as will hereinafter be more fully set forth and claimed. In theaccompanying drawings I have illustrated one complete example of thephysical embodiment of my invention in which the parts are combined andarranged according to the best mode I have thus far.

devised for the practical application of the principles of my invention.

Figure 1 is a perspective view of a truck p At the rear underside of thecarrier an arch bar or drop bar 11 extends transversely from embodyingmy invention. Figure 2 is a bottom plan view of the truck. Figure 3 is aside view of the truck in position to pick up a load. Figure 4 is adetail view at the rear or handle end of' the truck showing the swiv- Ieled steering wheel arrangement. Figure 5 is an enlarged detail of oneof the rockers for supporting the truck when in loading posi tion.Figure 6 is a perspective view of one of a pair of retaining devices forthe load located near the front of the truck. Figure 7 is a detail of aslightly modified form of] retaining device that may be substituted forthe device of Figure 6. Figure 8 is a per-' spective view of atriangular lug, used to assist in raising and holding boXes, etc.

In carrying out my inventlon I provide a 1929. Serial No. 364.791.

rigid, somewhat rectangular carrier or supporting frame for the load, asa barrel or keg, which frame or carrier comprises a pair of wooden sidebars 1, 1, cut away as at 2 along their upper, inner edges, toconform'to the shape of a barrel that is to be supported" inthe carrier.These side bars are oined by a rear cross plate 3 and a front'crossplate: 3, both of which are concaved toreceive a barrel or'keg and aresecurely riveted or bolted near their ends to the side bars 1, 1, of'thecarrier.

Thetruck may be manipulated by one man, through the instrumentality of acentral longitudinally disposed handle 4, that is' cut away at 5 at itsupper face to conform to the concave cross plates and the cut-away sidebars, for the reception of 'a barrel or keg. The handle} is rigidlyattached at the front and rear ends of the carrier or frame a'nd may Ibeused in up-ending the truck, as wellas for pushing, pulling andsteering the truck.

I At the front end of the carrier a transverse- 1y disposed axle 6 hasjournaled thereon "a pair of wheels 7, and as seen in Figure 1 the frontcross plate 3 has its opposite ends 8, .8

guarding these wheels against contact from a load.

At its underside the carrier is provided with an upper cross bar 9 and alower cross 'barlO that rigidly join the handle bar with carrier andbrace the latter at its unders1 e. j

These rockers aresecured to the side bars and theyare positiond so that the weight o i and loadofthe truck may betransferred from athej wheels to therockers, and vice versa', as
